+TI-NSPIRE timer
+
+Required properties:
+
+- compatible : should be "lsi,zevio-timer".
+- reg : The physical base address and size of the timer (always first).
+- clocks: phandle to the source clock.
+
+Optional properties:
+
+- interrupts : The interrupt number of the first timer.
+- reg : The interrupt acknowledgement registers
+ (always after timer base address)
+
+If any of the optional properties are not given, the timer is added as a
+clock-source only.
+
+Example:
+
+timer {
+ compatible = "lsi,zevio-timer";
+ reg = <0x900D0000 0x1000>, <0x900A0020 0x8>;
+ interrupts = <19>;
+ clocks = <&timer_clk>;
+};
+
+Example (no clock-events):
+
+timer {
+ compatible = "lsi,zevio-timer";
+ reg = <0x900D0000 0x1000>;
+ clocks = <&timer_clk>;
+};
